    How to install Windows 8 on machine with less than 1 GB RAM?


    For Windows 7, there is the ability to hex edit winsetup.dll so that Windows will install to any machine with any amount of RAM. In my online research, I've seen it be said that using the edited winsetup.dll from Windows 7 copied over the existing one for Windows 8 does not work at all.

    So my question is, does anyone know which values to edit in Windows 8 winsetup.dll to edit so that it can install well to a machine with less than 1 GB?

    My intention here is to get the awareness started with this so a successful solution can be produced.

    Thanks for reading.

    I suggest an alternative.

    You can avoid any error checking if you bypass windows setup and apply the windows image <mounted iso>\sources\install.wim to a formatted empty drive using imagex.exe, see what I wrote in:

    How did you setup your Win 8 install?

    SIW2 reported difficulties when he tried that method though.

    Less than 1 GB RAM may require that you boot with WinPE to run the installation via imagex.

    Hey ya, thanks for this. I just woke up not long ago and my brain is not functioning well at all yet haha. When I feel up to it most likely later on, I will check on everything!

    I am not completely confident however. If SIW2 is having issues, where is that gonna leave me at? lol

    For real though, I learned lots from him years ago just by hanging around.

    My HP nc6320 has 512mb. Windows 8CP installs without any problems. I'm using the "normal" setup methoud.
    (BTW: Windows 7 Ultimate also installs without problems).

    Interesting indeed!

    Did you boot to install media and make a custom (clean) install or did you upgrade a previous Windows version?

    No upgrade. Clean install from USB. W7 and W8 both install perfectly on 512mb.
    Control Panel/ System/ Installed memory (RAM) says: 512 MB (503 MB usable).
    Not sure how this would work on systems with eg. 512 MB minus 64/128 MB shared video RAM.

    What did you mean by "Boot to install media"?

    What I meant was, did you boot to the Windows installer on DVD or USB stick to install or did you install from within Windows already running?

    I tried upgrade installing Windows 8 CP from within Windows 7 SP1. The machine has 512 MB (383 MB usable) and it said that it can not do so.

    OK, thanks for explaining. I didn't do an upgrade install.
    Seems to me that if you have 383 MB usable memory (512-128mb shared video RAM, right?), things might run a little tight, specially if you want to install from *within* Windows 7. But I'm no expert in this field.
    On my 512 MB (503 usable) system, Windows 7 uses about 313 MB when running. Windows 8 uses about 264 MB when running.

    fafhrd, wish me luck. I am remoting right now into the machine with only 512 MB RAM and setting up partitions, downloading the WAIK and I'm going to attempt your methods out. I will be sure to post the results or any difficulties I run into. I plan to do this from Windows 7 C: partition to a new partition I am making now, both on the only HDD.

    At the moment, I'm running a nice space defrag so there will be least chance of issues making the new partition with Acronis.

    G'luck GMan.
    I have been having fun installing Windows Embedded Standard 8 onto a PC with 640MB RAM. The Image builder runs like a slug on temazepam compared with the corresponding product for Windows 7. You'll be finished before me!
